Tissue-Based MRI Intensity Standardization: Application to Multicentric Datasets

<table>Standardized images of the ADNI dataset, sorted according to MAE percentiles (A) 100, (B) 90, (C) 75, (D) 50, (E) 25, (F) 10, and (G) 0 obtained for the FRG voxel set with STI. Images (A) and (G) correspond, respectively, to the highest (worst) and lowest (best) MAE obtained in FRG for STI. From top to bottom: linearly registered input images, standard image, and images standardized with <svg height="15.25" id="M48" style="vertical-align:-3.276pt" version="1.1" viewbox="0 0 16.1625 15.25" width="16.1625" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink">
